[Industrial applications]

 The present invention relates to a transport bag called a flexible container bag, which is suitable for use in transporting a bulky material such as powder and granules, and more particularly to a mounting structure for a hanging hand thereof.

[0002]

[Prior Art]

 In recent years, a flexible container bag made of a base fabric made of synthetic resin stretched tape yarn, synthetic fiber yarn, etc. has been developed as a transport bag, which has contributed to rationalization in logistics. Since such a transport bag is used as a container transport container for bulky materials such as powder and granules, it is foldable, lightweight, has a simple structure, and is inexpensive. It has been used in large quantities in recent years. In this conventional transport bag, the hanging hand is attached to the base cloth by sewing. Hereinafter, the attachment structure of the hanging hand in the above-mentioned conventional transportation bag will be described with reference to the drawings.

FIG. 13 shows an example of a conventional transport bag, and is an enlarged view of a mounting portion of a hanger. As shown in FIG. 13, the transport bag body 51 is made of a base cloth woven of synthetic resin stretched tape yarn, synthetic fiber yarn, etc., and the body portion 52 is formed in a cylindrical shape. The hanger 53 is made of, for example, a synthetic resin stretched tape yarn and a synthetic fiber yarn having excellent strength, and is composed of a belt-shaped member in which the synthetic fiber yarn extends in the longitudinal direction. The hanger 53 is bent so as to be twisted at the central portion, and the mounting portions 54 on both sides thereof are juxtaposed side by side in the width direction, and the juxtaposed mounting portions 54 are superposed on the outer surfaces of the upper four portions of the body portion 52. Both of them are sewn together with a thread. The sewn portion is composed of a quadrangular frame sewn portion 55a that straddles both attachment portions 54, a linear sewn portion 55b in the diagonal crossing direction inside thereof, and a zigzag sewn portion 55c in the vertical direction (square frame). The sewing portion 55a, the linear sewing portion 55b in the diagonally intersecting direction, and the zigzag sewing portion 55c are continuously sewn by a sewing machine.)

FIG. 14 shows another example of a conventional transport bag, and is an enlarged view of a mounting portion of a hanger. In this conventional example, as shown in FIG. 14, as in the above-described conventional example, the strap 53 made of a belt-shaped member is bent so as to be twisted in the central portion, and the mounting portions 54 on both sides are brought close to each other in the width direction. The mounting portions 54, which are juxtaposed, are superposed on the outer surface of the upper portion of the body portion 52 of the transport bag main body 51 at four places, and both of them are sewn together with thread. The sewn portion is formed of a plurality of layers of annular sewn portions 55d which straddle both the attachment portions 54 and which are slightly elongated in the vertical direction and have a similar shape.

In any of the above-mentioned conventional transportation bags, for example, a pair of facing slings 53 are hooked with hanging strings (not shown), and hooks (not shown) of a crane are hooked on these hanging strings. Suspend and transport.

[0006]

[Problems to be solved by the device]

 However, among the above-mentioned conventional examples, a sewn portion including a rectangular frame sewing portion 55a such as the transport bag shown in FIG. 13, a linear sewing portion 55b in an oblique crossing direction, and a zigzag sewing portion 5c in the vertical direction. In the wearing structure, when the hanging string hung on the hanger 53 is hung by a hook of a crane or the like, the bent portion of the hanger 53 is compressed into a fold shape as shown by a chain line, whereby both side portions 54a of the attachment portion 54 are Tends to be gradually separated from the body portion 52 as it goes from the lower portion to the upper portion. When a load is applied to the mounting portion 54 in this state, a force is applied to the corners of the rectangular frame sewn portion 55a and the straight line sewn portion 55b in the diagonally intersecting direction together with the load in the direction of separating the mounting portion 54 from the body portion 52. As a result, the sewing thread cuts relatively easily.

In addition, as described above, in the hanger 53, the belt-shaped member is bent so as to be twisted at the central portion, the mounting portions 54 on both sides thereof are aligned in the width direction, and the parallel mounting portions 54 are stacked on the body portion 52. In addition, since the hanger 53 is sewn, and the hanger 53 is hard to stretch and is woven from a hard material, and the whole is relatively hard, the edge 54b of the mounting portion 54 located outside the transport bag main body 51 at the bent portion is bent. Due to the restoring force of the twist of the portion, it tends to be separated from the body portion 52. However, in the above-mentioned conventional example, since the rectangular frame sewing portion 55a, the linear sewing portion 55b, and the zigzag sewing portion 55c all straddle both the attachment portions 54, the load at the time of suspension is not affected. Together, the sewing thread in this straddle section cuts relatively easily. When the sewing thread is cut at the corners and the intermediate portion in this way, it is cut sequentially, and finally the whole is cut, resulting in poor sewing strength.

On the other hand, in the configuration of the transport bag shown in FIG. 14, when the hanger 53 is hung, the bent portion of the hanger 53 is compressed into a fold shape, so that both sides of the mounting portion 54 are similarly compressed as described above. Even if the part 54a is gradually widened from the lower part to the upper part and is inclined away from the body part 52, the part is sewn in an annular shape, and both sides of the upper part are curved and escape, so that the sewn part is separated from the upper part. Less likely to receive force. However, since each annular sewn portion 55d straddles both attachment portions 54, the edge portion 54b side of one attachment portion 54 is separated from the body portion 52 by the restoring force of the twist of the bending portion, as in the above-described conventional example. Since they tend to be pulled apart, the sewing thread in the portion straddling both attachment portions 54 is relatively easily cut, and the sewing strength is insufficient.

The present invention solves the above-mentioned problems of the conventional example, and can improve the sewing strength of the hanging hand, and thus can improve the reliability and durability. The purpose is to provide a shipping bag.

[0010]

[Means for Solving the Problems]

 The technical means of the present invention for achieving the above-mentioned object is to bend a hanger made of a belt-shaped member, and to attach the attachment parts on both sides of the hanger in a juxtaposed and juxtaposed manner to the body of the transport bag body. The sewn portion of each of the above-mentioned mounting portions is a frame-shaped sewn portion, an inclined straight line sewn portion bent inside the frame-shaped sewn portion, and both upper end portions of the frame-shaped sewn portion. And an arcuate sewing portion that bulges upward in an arcuate shape.

Another technical means of the present invention for achieving the above-mentioned object is to bend a hanger made of a belt-shaped member, and to attach the both side parts of the hanger in a parallel state in which the mounting parts on both sides of the hanger are separated from each other. The sewn portion of each of the above-mentioned attachment portions is a frame-shaped sewn portion, an inclined straight line sewn portion bent inside the frame-shaped sewn portion, and the frame-shaped sewn portion. The upper part of the part is composed of an arcuate sewing part which bulges upward from both sides in an arcuate shape.

The body portion of the transport bag body may be formed in a rectangular tube shape, and the attachment portions on both sides of the hanger may be sewn separately on both side surfaces of the corner portion of the body portion.

In the above technical means, when each attachment part of the hanger is sewn to the body part, each attachment part can be sewn to the reinforcing part formed in the body part in the longitudinal direction.

[0014] In the above technical means, when sewing each attachment part of the hoisting member to the body part, a reinforcing part is formed on the upper part of the body part by folding back to the outer surface, and each attaching part of the hoisting part is attached to the reinforcing part and A reinforced portion is formed by sewing on the body or by folding it back to the outside on the upper part of the body and folding it back into the body. Can be sewn to the body and the body.

In the above technical means, when the attachment parts on both sides of the hanger are sewn to the body part, they can be sewn together with the vertical reinforcing belt sewn vertically to the body part.

It is preferable that the arcuate sewn portions are arranged in a plurality of stages, and each sewn portion is repeatedly sewn.

[0017]

[Action]

 According to the present invention configured as described above, when the hoist is suspended by the hoist, the attachment parts on both sides of the hoist are respectively formed by the frame-shaped sewing portion, the inclined straight-line sewing portion, and the arc-shaped sewing portion. Since the sewing thread is sewn in the direction of the seed, the load can be distributed over the entire sewn portion. In addition, when the hoist is hung, the bent part of the hoist is compressed like a fold, and as a result, both sides of the mounting part tend to be gradually separated from the body side as they go from the lower part to the upper part. In addition, since the arcuate sewn part at the top of each attachment part is bulged upward from both sides of the upper end of the frame-shaped sewn part and escapes, it is difficult for the sewing thread to receive the force in the above separating direction and cut. It gets harder. In addition, since each attachment portion is sewn separately by the frame-shaped sewn portion, the inclined straight line sewn portion, and the arc-shaped sewn portion, these sewn portions are prevented from straddling both attachment portions. Even if the side edge of the attachment part tends to be separated from the body side due to the restoring force of the twist of the bending part in the lifting hand itself, there is no possibility that this separation force will be applied to one place of each sewing part as in the past. Since there is no sewing thread, it becomes difficult to cut the sewing thread.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, a first embodiment of the present invention will be described. 1 to 3 show a first embodiment of a transport bag according to the present invention, FIG. 1 is an overall front view, FIG. 2 is a partial schematic sectional view, and FIG. 3 is an enlarged view of a main part.

As shown in FIG. 1 to FIG. 3, the transport bag body 1 is made of synthetic fiber, or a base cloth obtained by weaving a synthetic resin stretched tape yarn or the like, or one or both sides of the above-mentioned weaving cloth made of a synthetic resin film. It is composed of a base fabric laminated and waterproofed. As an example thereof, the body 2 is formed in a rectangular tube shape, and the main parts except for the strip-shaped portions on both sides of each corner are woven with a weft thread and a warp thread made of polyethylene, polypropylene or the like, and the strip-shaped portions on both sides of each corner are made of polyethylene. A weft yarn made of polypropylene or the like and a warp yarn made of polyester (Tetron) or the like are woven together to form a longitudinal strip-shaped reinforcing portion 3 and laminated with a film of polypropylene or the like. The outer edge of the bottom surface 4 is sewn and integrated with the lower end edge of the body portion 2. A chrysanthemum 5 is formed in the center of the bottom surface 4, and a base of a cylindrical discharge port 6 is sewn to the inside of the center of the bottom surface 4. A string loop 7 is formed on the lower edge of the chrysanthemum seat 5, a string 8 is inserted through the string loop 7, and both side protrusions of the string 8 are inserted through the binding tube 9 so that a knot is formed and prevented from coming off. .. The intermediate portion of the outlet tape 10 is sewn to the outside of the intermediate portion of the outlet 6. A frustoconical inlet 11 and a base of an outer chrysanthemum 12 are sewn and integrated with the upper end edge of the body 2. The middle portion of the inlet tape 13 is sewn on the outside of the middle portion of the inlet 11. A string loop 14 is formed on the upper edge of the chrysanthemum seat 12, a string 15 is inserted through the string loop 14, both side protrusions of the string 15 are inserted through the binding tube 16, and a knot is formed to prevent the string from coming off. .. In this embodiment, the transport bag body 1 has an inner bag 17 made of polyethylene film or the like inside, and its upper end is folded back to the outside of the upper end of the inlet 11 and is fixed by an adhesive tape 18.

The hanger 20 attached to the four corners of the body portion 2 of the transport bag body 1 is, for example, a synthetic resin tape yarn such as polypropylene and a synthetic fiber yarn such as polyester which is excellent in strength and does not easily stretch. The synthetic fiber yarn extends in the longitudinal direction and is composed of a band member having a relatively high hardness. The hanger 20 composed of this belt-shaped member is bent so as to be twisted at the central portion, and the mounting portions 21 on both sides thereof are arranged in close proximity to each other in the width direction. Divided on both sides of the corners, they are superposed on the belt-shaped reinforcing portion 3 and attached to the body portion 2 by sewing with a thread by a sewing machine.

The sewn portion of each attachment portion 21 includes a frame-shaped sewn portion 22, an inclined linear sewn portion 23 bent inside the frame-shaped sewn portion 22, and a sewn portion of the frame-shaped sewn portion 22. It is composed of arcuate sewing portions 24, 25 which bulge upward from both sides of the upper end in a circular arc shape. The frame-shaped sewn portion 22 is substantially parallel to the axial center of the body portion 2, and the side sewn portion 26 along the side edge of the attachment portion 21 and the arc-shaped upper stitch connecting the upper ends of the side sewn portions 26 are connected. And a wearing part 27. The inclined linear sewing portion 23 is a linear portion connecting both lower ends of the side sewing portion 26 and the central portion of the upper sewing portion 27, and both upper ends of the side sewing portion 26 and the side sewing portion. 26, a straight line portion that connects the central portion between the lower ends and that intersects with the straight line portion. The arcuate sewn portions 24 and 25 arranged in a plurality of stages, two stages in the illustrated example, are all wrapped upward from both upper ends of the frame-shaped sewn portion 22. Any of the arcuate sewn portions 24 and 25 is sewn repeatedly a plurality of times. In this example, the inner arcuate sewn portion 24 is sewn twice and the outer arcuate sewn portion 25 is sewn three times. It is sewn repeatedly. The frame-shaped sewn portion 22, the inclined linear stitched portion 23, and the arc-shaped sewn portions 24 and 25 of each mounting portion 21 are continuously sewn by the sewing machine, and the adjacent frame-shaped sewn portion 22 is sewn. The upper and lower ends are continuous by continuous sewing portions 28 and 29 so that they are continuously sewn together by a sewing machine.

For example, a hanging string 30 is hung on a pair of the hanging hands 20 facing each other.

In the above configuration, the usage procedure will be described below. First, the discharge port 6 is detachably bound by the discharge port tape 10 and stored inside the chrysanthemum seat 5, and the binding tube 9 is moved to reduce the loop of the string 8 and close the chrysanthemum seat 5. Next, after storing the powdered particles or the like through the input port 11, the input port 11 is bound by the input port tape 13 and stored inside the chrysanthemum 12, and the binding tube 16 is moved to remove the loop of the string 15. Make it smaller and close Kikuza 12. After storing the powder or the like in this manner, the hanging hook 30 of the crane is hooked on the hanging string 30 hung on the hanging hand 20, and the hanging string is carried.

After the transportation, in order to discharge the granular material or the like, a hook such as a crane is hung on the hanging strap 30 hung on the hanging hand 20, and the transportation bag is hung. After that, when the loop of the string 8 is enlarged by moving the binding tube 9, the discharge port 6 opens the chrysanthemum 5 and projects downward due to the weight of the granular material or the like. Then, by loosening the discharge port tape 10, the granular powder or the like can be discharged from the discharge port 6 by its own weight.

Then, as described above, the hanger 20 is sewn by the frame-shaped sewn portion 22, the slanted linear stitched portion 23, and the arc-shaped sewn portions 24 and 25 in various directions. Since it is sewn to No. 2, the load can be distributed over the entire sewn portion. Further, the bent portion of the hanger 20 is compressed into a fold shape (see FIGS. 13 and 14), whereby the side edge portion 21a of the mounting portion 21 is gradually separated from the body portion 2 as it goes from the lower portion to the upper portion. Even if it is attempted, since the arcuate sewing portions 24, 25 on the upper portion of each attachment portion 21 are bulged upward from both upper end portions of the frame sewing portion 22, the force of the sewing thread in the direction of pulling apart It is hard to receive, and moreover, the arcuate sewing portions 24 and 25 of a plurality of steps are sewn by repeating a plurality of times to increase the sewing strength, so that it is difficult to cut. In addition, each attachment portion 21 is sewn separately by the frame-shaped sewn portion 22, the inclined straight-line sewn portion 23, and the arc-shaped sewn portions 24, 25, and these sewn portions 22, 23, 24, Since 25 does not straddle both attachment portions 21, the side edge portion 21b of the attachment portion 21 tends to be separated from the body portion 2 side by the restoring force (repulsion elasticity) of the twist of the bent portion of the lifting hand 20 itself. However, since there is no possibility that this separating force will be applied to one place of each sewing portion 22, 23, 24, 25 unlike in the conventional case, the sewing thread is difficult to cut. Therefore, the sewing strength can be improved.

As the first embodiment of the present invention and the conventional example shown in FIGS. 13 and 14 which are the first and second comparative examples thereof, the body portions 2 and 52, the slings 20 and 53, and the sewing Transport bags were manufactured by using the same conditions as the following yarns.

The main parts of the body parts 2 and 52 are made of polypropylene tape yarn (1500 denier, width 5 mm, thickness about 400 microns) for warp and weft, and weaved with 15 × 15 number of threads (between inches), The belt-shaped reinforcing portion 3 uses a filament yarn (3900 denier) made of polyester (Tetoron) for the warp yarn, and a polypropylene tape yarn (1500 denier, width 5 mm, thickness about 400 microns) for the weft yarn, and the number of stitches (between inches) 7 The woven cloth was woven at 0.5 × 15, and one side of the woven cloth was coated with a polypropylene film (about 40 μm thick) to form a base cloth. 80-90 polypropylene tape yarns (6000 denier, width 1 mm, thickness 0.8 mm) were juxtaposed for the warp threads 20 and 53, respectively, and warp threads were woven using polyester threads. As the sewing thread, one-ply thread made of polyester (1500 denier or 2000 denier) was used.

Then, as a result of testing the sewing strength of each of the hanging hands 20 and 53, in the first comparative example (conventional example), the cutting of the sewing thread starts under a load of 1100 kg, and the second comparative example ( In the conventional example), the cutting of the sewing thread started at 1300 kg, and in the embodiment of the present invention, the cutting of the sewing thread started at a load of 1500 kg. As is clear from the test results, the sewing strength of the second comparative example could be improved by 15 to 20% by using the lifting attachment structure of the present invention.

FIG. 4 is an enlarged view of a main part showing a modified example of the sewn portion in the first embodiment. In this example, the upper sewn portion 27 of the frame-shaped sewn portion 22 is oriented straight in a direction perpendicular to the side sewn portion 26, and other configurations are the same as above. Therefore, the same portions are denoted by the same reference numerals and the description thereof will be omitted.

Next, a second embodiment of the present invention will be described. 5 to 7 show a second embodiment of the transport bag of the present invention, FIG. 5 is a front view of the whole, FIG. 6 is a partial schematic sectional view, and FIG. 7 is an enlarged view of a main part. FIG. 8 is an enlarged view of a main part showing a modified example of the sewn part.

In the present embodiment, as shown in FIGS. 5 to 8, the reinforcing portion 31 is formed by being folded back to the outer surface and sewn on the upper portion of the body portion 2 of the transport bag body 1. .. The inner bag 17 is not used in the transport bag body 1 in this embodiment. Then, the attachment portions 21 on both sides of the hanging hand 20 are separated from each other and are divided into both side surfaces of the corner portion of the body portion 2 and overlapped on the reinforcement portion 31 and the body portion 2 at the position of the strip-shaped reinforcement portion 3, Each mounting portion 21 is sewn to the reinforcing portion 31 and the body portion 2 by a frame-shaped sewing portion 22, a slanted linear sewing portion 23, and arc-shaped sewing portions 24 and 25 made of a sewing thread. A suspension ring 32 is linked to each of the hanging hands 20, and the suspension ring 32 is configured to be suspended. The rest of the configuration is similar to that of the first embodiment, so the same parts are designated by the same reference numerals and the description thereof is omitted.

Also in this embodiment, as described above, the hanger 20 is sewn with the frame-shaped sewn portion 22, the inclined linear sewn portion 23, and the arc-shaped sewn portions 24, 25 oriented in various directions. Since the body portion 2 is sewn with the thread, the load can be distributed over the entire sewn portion. In addition, the bent portion of the hanger 20 is compressed into a pleated shape (see FIGS. 13 and 14), whereby the side edge portion 21a of the mounting portion 21 gradually separates from the body portion 2 as it goes from the lower portion to the upper portion. However, since the arcuate sewn portions 24, 25 at the upper part of each attachment portion 21 are bulged upward from both upper end portions of the frame-shaped sewn portion 20, the sewing thread is separated in the above-mentioned direction. Of the circular arc-shaped sewing portions 24, 25 are sewn to the reinforcing portion 31 and the body portion 2 by repeating a plurality of steps a plurality of times to increase the sewing strength, so that it is difficult to cut. In addition, each attachment portion 21 is sewn separately by the frame-shaped sewn portion 22, the inclined straight-line sewn portion 23, and the arc-shaped sewn portions 24 and 25, and these sewn portions 22, 23, 24 and 25 are sewn separately. Since it does not straddle both the attachment portions 21, even if the side edge portion 21b of the attachment portion 21 tends to be separated from the body portion 2 side due to the restoring force of the twist of the bent portion of the lifting hand 20 itself. Since there is no possibility that this separating force will be applied to one place of each sewn portion 22, 23, 24, 25 as in the conventional case, the sewing thread is difficult to cut. Therefore, the sewing strength can be improved.

With the configuration shown in FIGS. 5 to 7 in the present embodiment, a transportation bag was manufactured under the same conditions as in the first embodiment, and the sewing strength of the hanger 20 was tested and the result was 1800 kg or more. The sewing thread started to be cut under the load. As is clear from this test result, the sewing strength of the second comparative example could be improved by about 40% by using the hanging attachment structure of the present invention.

Next, a third embodiment of the present invention will be described. 9 to 11 show a third embodiment of the transport bag of the present invention, FIG. 9 is a front view of the whole, FIG. 10 is a partial schematic sectional view, and FIG. 11 is an enlarged view of a main part. FIG. 12 is an enlarged view of a main part showing a modified example of the sewn part.

In this embodiment, as shown in FIG. 9 to FIG. 11, the upper part of the body 2 of the transport bag body 1 is folded back to the outer surface, and then folded and sewn between the body 2 and the body 2. As a result, the reinforcing portion 33 is formed. The transport bag body 1 in this embodiment is not provided with the chrysanthemum 12 outside the charging port 11. Then, the mounting portions 21 on both sides of the hanger 20 are separated from each other and are divided into both side surfaces of the corner portion of the body portion 2 and are stacked on the reinforcing portion 33 and the body portion 2 at the position of the strip-shaped reinforcing portion 3, Each attachment portion 21 is sewn to the reinforcing portion 33 and the body portion 2 by a frame-shaped sewing portion 22, a slanted linear sewing portion 23, and arc-shaped sewing portions 24 and 25 made of sewing thread. A suspension ring 32 is linked to each of the hanging hands 20, and the suspension ring 32 is configured to be suspended. The other structure is similar to that of the first and second embodiments, and therefore, the same reference numerals are given to the same portions and the description thereof will be omitted.

Also in this embodiment, as described above, the hanger 20 is sewn by the frame-shaped sewn portion 22, the inclined linear sewn portion 23, and the arc-shaped sewn portions 24, 25 in various directions. Since the body portion 2 is sewn with the thread, the load can be distributed over the entire sewn portion. In addition, the bent portion of the hanger 20 is compressed into a pleated shape (see FIGS. 13 and 14), whereby the side edge portion 21a of the mounting portion 21 gradually separates from the body portion 2 as it goes from the lower portion to the upper portion. However, since the arcuate sewn portions 24, 25 at the upper part of each attachment portion 21 are bulged upward from both upper end portions of the frame-shaped sewn portion 20, the sewing thread is separated in the above-mentioned direction. Is not easily received, and moreover, the arcuate sewn portions 24 and 25 of a plurality of steps are repeatedly sewn to the reinforcing portion 33 and the body portion 2 to increase the sewn strength, and thus are difficult to cut. In addition, each attachment portion 21 is sewn separately by the frame-shaped sewn portion 22, the inclined straight-line sewn portion 23, and the arc-shaped sewn portions 24 and 25, and these sewn portions 22, 23, 24 and 25 are sewn separately. Since it does not straddle both the attachment portions 21, even if the side edge portion 21b of the attachment portion 21 tends to be separated from the body portion 2 side due to the restoring force of the twist of the bent portion of the lifting hand 20 itself. Since there is no possibility that this separating force will be applied to one place of each sewn portion 22, 23, 24, 25 as in the conventional case, the sewing thread is difficult to cut. Therefore, the sewing strength can be improved.

The reinforcing belt in the vertical direction may be sewn in place of the strip-shaped reinforcing portion 3 in each of the above embodiments. Further, the vertical reinforcing portion 3 and the reinforcing belt may be omitted. In addition, in each of the above-described embodiments, the outer circumference of the body portion 2 may be sewn on the outer circumference of the body portion 2 from above the attachment portion 21 of the hanger 20 for reinforcement. Besides, the present invention can be variously modified in design without departing from the basic technical idea.

[Effect of the device]

 As described above, according to the present invention, the hanger made of a belt-shaped member is bent, and the attachment portions on both sides of the hanger are sewn to the body of the transport bag body in a juxtaposed parallel state or in a juxtaposed parallel state. The sewn part of each of the above-mentioned attachment parts is a frame-shaped sewn part, an inclined straight line sewn part bent inside the frame-shaped sewn part, and both upper ends of the frame-shaped sewn part. And an arcuate sewing portion that bulges in an arcuate shape from the above portion. Then, when hanging down with the hanger, direct the attachment parts on both sides of the hanger to various directions by the frame-shaped sewing part, the slanted linear sewing part, and the arc-shaped sewing part as described above. Since the sewing is performed with the sewing thread, the load can be distributed over the entire sewing portion. In addition, when the hoist is hung, the bent part of the hoist is compressed into a fold, which tends to gradually pull apart from the torso as both sides of the mounting part go from the lower part to the upper part. Also, since the arcuate sewn parts on the tops of the attachment parts are bulged upward from both sides of the upper end of the frame-shaped sewn parts as described above, the sewing thread does not exert a force in the direction of separation. Difficult to receive and cut. Further, as described above, each attachment portion is sewn separately by the frame-shaped sewn portion, the inclined straight line sewn portion, and the arc-shaped sewn portion so that these sewn portions do not straddle both attachment portions. Therefore, even if the side edge of the attachment part tends to be separated from the body side due to the restoring force of the twist of the bending part of the lifting hand itself, this separating force is different from the conventional sewing parts. Since it is not likely to be applied to one place, the sewing thread will be difficult to cut. As a result, it is possible to improve the sewing strength of the body of the hanging hand, and thus to improve the reliability and durability.

In addition, the body portion of the transport bag body is formed in a rectangular tube shape, and the attachment portions on both sides of the hanging portion are separately sewn on both side surfaces of the corner portion of the body portion to bend the hanging portion of the hanging portion. Therefore, the twisting can be reduced, and therefore, the sewing work can be easily performed and the sewing strength can be improved.

Further, by sewing the attachment portions on both sides of the hanger to the reinforcing portion formed in the body in the vertical direction, the sewing strength can be further improved.

In addition, when sewing each attachment part of the hanger to the body part, a reinforcement part is formed on the upper part of the body part by folding back to the outer surface, or on the upper part of the body part, folding back to the outer surface and this folding back.
